Explore how optical genome technology works
The OGM workflow starts with mega-base size DNA isolation. A single enzymatic reaction labels the genome at a specific sequence motif occurring approximately 15 times per 100 kbp in the human genome. The long, labeled DNA molecules are linearized in nanochannel arrays on a Saphyr Chip® and imaged in an automated manner by the Saphyr Instrument. Using pairwise alignments, the molecules are assembled into local maps or whole genome de novo assemblies. Changes in patterning or spacing of the labels are detected automatically, genome-wide, to call all structural variants.
